12 men complete a work in 14 days. 5 days after they had started working, 3 men join them. How many more days will all of them take to complete the remaining work?
Correct Answer: 3
Explanation:
Let p be the required number of days.
From the given data,
12 x 14 = 12 x 5 + (12+3) x p
12 x 14 = 12[5 + 3p]
14 = 5 + 3p
3p = 9
p = 3 days.
Hence, more 3 days all of them take to complete the remaining work.
